#973: ST_GetFaceGeometry - don't intercept the UniverseFace
 Reporter:  aperi2007  |       Owner:  strk         
     Type:  defect     |      Status:  assigned     
 Priority:  medium     |   Milestone:  PostGIS 2.0.0
Component:  topology   |     Version:  trunk        
 Keywords:             |  

Comment(by strk):

 The specs say that ST_GetFaceGeometry should use ST_GetFaceEdges to
 construct the face, and the description of ST_GetFaceEdges does not say
 anything special about the universal face.

 I don't see NULL being returned, but a multipolygon, where each "hole" in
 the universal face is represented as a polygon. This is equivalent to the
 union of all faces.

 If not backed up by specs, do we still want to throw an exception here ?
